Thanks Jo Anna, main part of your post is that you know the person and that it was doctor diagnosed. |
I thoght it may be useful information to know what part of town your friend lived in as I have always thought that mosquitos usually stayed within 100 yards of home. I searched that and discovered its not true so I debunked my own belief.
The average mosquito flies at about 1.5 miles per hour, and will not go far away from the area that they were hatched. Most will only fly about one to three miles in search of food. But this is really dependent on the species of mosquito. In the midwest, certain species will fly up to seven miles away searching.
Mosquitoes tend to stay below twenty five feet when searching for food. When they reach higher altitudes, it is easier for the wind to pick them up and sweep them away from their home location.
I remember reading that previously having Dengue could be a plus when positive for coronavirus. I did a search and didn't read further than the results page as I saw several conflicting titles and realized that it is just like everything else COVID related i.e. confusing.
Here are some various notes of interest I copy pasted while reading a few sources.
Female Ae. aegypti frequently feed multiple times between each egg-laying period . Once a female has laid her eggs, these eggs can remain viable for several months, and will hatch when they in contact with water.
Aedes albopictus, a secondary dengue vector in Asia, has spread to more than 32 states in the USA, and more than 25 countries in the European Region, largely due to the international trade in used tyres (a breeding habitat) and other goods (e.g. lucky bamboo). Ae. albopictus is highly adaptive. Its geographical spread is largely due to its tolerance of colder conditions, as an egg and adult [21, 22]
Many people experience no signs or symptoms of a dengue infection.
After you've recovered from dengue fever, you have long-term immunity to the type of virus that infected you — but not to the other three dengue fever virus types. This means you can be infected again in the future by one of the other three virus types. Your risk of developing severe dengue fever increases if you get dengue fever a second, third or fourth time.
Signs and symptoms
typically, people infected with dengue virus are asymptomatic (80%) or have only mild symptoms such as an uncomplicated fever
Severe disease is more common in babies and young children, and in contrast to many other infections, it is more common in children who are relatively well nourished. Other risk factors for severe disease include female sex, high body mass index, and viral load.
Generalized spraying with organophosphate or pyrethroid insecticides, while sometimes done, is not thought to be effective.
A vaccine for dengue fever has been approved and is commercially available in a number of countries. As of 2018, the vaccine is only recommended in individuals who have been previously infected, or in populations with a high rate of prior infection by age nine.
Rates of dengue increased 30 fold between 1960 and 2010. This increase is believed to be due to a combination of urbanization, population growth, increased international travel, and global warming.
